Fab purchased!!

I’ve spent a fortune over the years trying to find suitable underwear for a very large bust. I’ve lost count how many bras I’ve purchased that have been an utter waste of money. I finally found one that was fantastic but has stopped being made so I was on the hunt once more. I regularly shop with decathlon so thought I’d give them a try. I was very sceptical of this bra mainly due to the price. I didn’t have high hopes but I also don’t have a fortune to keep taking chances. Well I can honestly say I’m shocked at how good this bra is. I run 3-4 times a week and need ample support and this bra definitely does the job. I’ve worn it 5-6 times and am so impressed I’ve ordered another already. The top clip is a game changer!

Running bra

2 one of this bra I’ve purchased. Being a 32f I think I’m a great test for it and it’s the best running bra I’ve ever had.

Kalenji running bra

Really pleased with this bra, comfortable and very supportive

Great support and very comfy

As a larger sized lady, this bra was very comfortable. Very little ‘bounce’ and movement. Nice wide straps and sits well under the boobs. Extra support achieved with the racer back clip. Smooth fabric and it has high support around the cleavage area. Great purchase.

Amazing comfort, great support and keeps you dry.

Fantastic item not as aspected and to be honest off the hanger I didn’t expect much as I thought it was more like a swimming costume fabric. On though it won me over immediately and I am going in search of some more at another store. It’s comfy, supportive, keeps you dry in this warm weather and the wider straps help reduce back ache. It’s hard to find a 40E bra that does all this.

Good quality

Bra is made well and worth the money, but I did return mine as it was not the righ fit for me. Not many options for sizes

Life changer!!

The most comfortable, and effective bra, with added clips for extra support, that Iv ever worn. Sports bras for bigger sizes are hard to find, especially comfy ones! Very impressed. Come up slightly smaller so I needed next size up. Otherwise really good quality bra. I have several since my first purchase a few months ago.

Absolute fan

I go to Decathlon to buy sports related products, however this bra has now become an every-day product for me. I recently put on a lot of weight due to an operation. Therefore I felt really conscious about bouncing breasts with every step I took. I tried many bras but this is the absolute best. I don't feel self-conscious anymore when walking and doing sports because I feel fully supported and therefore more confident. Great idea about the solution at the back too. I am now on my second bra - only because I slowly start losing weight again - and this is a great companion along the way.

Very comfortable

I love this sports bra! I should get a couple. The added feature of making it a racer back is superb as well for making those style sports top more stylish without unsightly bra straps. Its very comfortable, I use it for running long miles and cycling without any bra rash!

Brilliant sports bra

I ordered my usual size, 34E, and it fits really well. Very comfortable to wear and really supportive. I ran a half marathon in it the first time I wore it and thought it was great. Far more comfortable than the shock absorbers I was wearing before. Highly recommend,

How is the maximum level of support (level 5 on a scale from 1 to 5)of this running bra guaranteed?

All our products are passed by our bust support test (measurement of the decrease in breast bounce when running) conducted in our laboratories. They are evaluated and given a rating from 1 (low support) to 5 (high support). Like all the KALENJI models, this sports bra was given a level 5 rating and is suitable for all HIGH IMPACT sports. *This sports bra reduces bounce by 46% compared with a conventional bra when practicing HIGH IMPACT sports.

What type of cups does the large size running bra have?

The Large Size sports bra has 2 flexible double-thickness cups (non-molded) and is perfectly tailored to busts up to an F-cup.We also offer sports crop tops and bras with breathable molded cups.

How was this large size running bra designed?

We designed a sports bra for optimum comfort and breast protection: As with all KALENJI models: * we do not use underwiring (risk of injury or of compressing the glands) * we keep the number of seams around the nipples to a minimum (risk of irritation) * we use components that wick away perspiration (this criterion improves comfort while also considerably diminishing the risk of irritation).

And what if the back length is too small?

If the cup size suits you, but you need to be able to adjust the back, you can use the 57 mm KALENJI BACK EXTENSION.

A score to compare the environmental impact of products

The environmental impact of the product is calculated across its entire lifecycle using a range of indicators.

Product testing

SUPPORT: the support was tested and approved by testers in the DECATHLON laboratory. Each size was tested separately. PERSPIRATION WICKING: the perspiration wicking test was conducted on each material in the laboratory to check that the fabric absorbs and transfers moisture from the inside of the fabric outward and eliminates it. WASHING: The washing and drying tests guarantee good stability (dimensional stability and colorfastness)

Care instructions

Machine washable at 86°F max. Synthetic cycle. Use liquid detergent, preferably. Do not use fabric softener Do not tumble dry Do not dry clean Do not use bleach
